Question

我搜索问题是否已被提出但我没有找到任何答案。我使用ruby版本2.3.0和rails版本5.0.0.1创建了一个应用程序，

当我运行此命令时

rails console

我尝试像这样访问db：

Post.all
User.all

或者其他命令行我有这个巨大的错误（抱歉所有这些行：

 end

和

rails console

Answer 4

如果您仍然遇到问题，请尝试以下步骤：

通过运行以下命令使用 npm 安装 webpacker：npm i @rails/webpacker 运行捆绑安装注意：您可能需要删除版本名称。如果是这样，请执行以下操作：
在您的 Gemfile 中：将带有 webpacker gem 的行更改为： gem 网络打包器
```
Delete the gemfile.lock file
Run bundle install
```
手动添加一个名为 webpacker.yml 的文件到 config 目录（最终路径：./config/webpacker.yml）。
```
Add this text to the webpacker.yml file:
```
